IPC: C07C311/54
Filed: 1964-12-14
Abstract: The invention comprises sulphonyl ureas of the formula <FORM:1089197/C2/1> and their physiologically tolerable salts, wherein R1 is a C1- 8 alkyl, C5- 8 cycloalkyl or ((C5- 8 cycloalkyl)-alkyl group having 1-3 carbon atoms in the alkyl portion, X is a hydrocarbon group of 1 or 2 carbon atoms, e.g. methylene, ethylene, ethenylene or ethylidene and R2 is (a) a C2- 8 alkyl group, (b) a phenyl-C1- 3 alkyl or cyclohexyl-C1- 3 alkyl group, (c) an endoalkylenecyclohexyl, -cyclohexenyl, -cyclohexylmethyl or -cyclohexenylmethyl group containing 1 or 2 endoalkylene carbon atoms, (d) a C1- 4-alkylcyclohexyl group, or (e) a C5- 8 cycloalkyl group. The compounds are prepared by (a) reaction of an R1OOC.X- substituted benzenesulphonamide (suitably in the form of a salt) with an isocyanate R2CNO or a corresponding carbamic acid ester or halide, thiocarbamic ester, urea or N2-substituted urea, (b) reaction of an amine R2NH2 or a salt thereof with a benzenesulphonyl urea isocyanate, R1OOC.X.C6H4.SO2-NCO or a corresponding carbamic ester or halide, thiocarbamic ester, urea or N2-substituted urea, (c) reaction of a benzenesulphonyl chloride R1OOC.X.C6H4.SO2Cl with an R2 substituted urea, isourea ether, isothiourea ether or parabanic and hydrolysis of a benzenesulphonyl isourea ether, isothiourea ether or parabanic acid obtained in this way or by another method, (d) exchange of the sulphur atom in a corresponding benzenesulphonylthiourea for an oxygen atom by oxidation or reaction with a heavy metal salt, and (e) oxidation of a corresponding benzenesulphenyl or benzenesulphinyl urea.  If desired, carboxylic acids HOOC.X.C6H4.SO2.NH.CO.NHR2 formed by the above reactions or in another way may be esterified to introduce the group R1. Alternatively a compound wherein X is -CH = CH- may be hydrogenated to form a product wherein X is -CH2-CH2-.  4 - Sulphamoyl - phenylacetic acid is made by chlorosulphonating phenylacetic acid and reacting the resulting acid chloride with ammonia.  N - (4 - Carbo - n - butoxy - methyl - benzenesulphonyl)-urea is made by the action of potassium cyanate on the corresponding benzenesulphonamide. 4 - b  - Carbethoxyvinyl - benzenesulphonamide is made by esterifying the free acid.  N - 4 - Carbethoxymethyl - benzenesulphonyl - N1-cyclohexyl-urea is made by the action of chloroformic methyl ester on the corresponding sulphonamide.  Pharmaceutical preparations for the treatment of diabetes comprise the above compounds of the invention in admixture or conjunction with a carrier, preferably in a form suitable for oral administration such as tablets.

Title: Powered hydrualic braking systems
IPC: B60T13/14
Filed: 1973-11-02
Abstract: 1453962 Hydraulic power assisted brake systems AISIN SEIKI KK 2 Nov 1973 [14 Nov 1972] 51109/73 Heading F2F Hydraulic fluid flows from a pressure source via a main control valve and a subcontrol valve operated by, e.g. wheel skid detectors to one or more wheel brake slave cylinders, the subcontrol valve alternatively communicating the cylinders with a reservoir via a safety valve which blocks communication therewith only if upon main control valve actuation the pressure source fails. In Fig. 1 an engine driven pump 10 feeds an accumulator 16 via a charging valve which allows flow back to the reservoir 12 if the accumulator is at the required pressure. Upon pedal actuation, a piston controlled thereby in the main control valve 22 moves a ball into contact with a spring biased hollow stem to block communication between the reservoir 12 and the subcontrol valve 53. Further piston movement moves an external shoulder of the stem from a seating to open communication between the accumulator 16 and the valve 53. The subcontrol valve 53 has a cupped disc holding a member against a seating to block an outlet from a chamber on one side of a hollow spool so that chambers on either side of the spool, which communicate via a restricted orifice, are at equal pressures. In this condition the spool allows communication between the valve 22 and the slave cylinders 83. Upon receipt of a brake release wheel skid signal, the cupped disc valve member is actuated by a solenoid to allow fluid flow from the one chamber so that the spool moves to block valve 22-cylinders 83 communication and to open cylinders 83-safety valve 81 communication. If the pressure source fails, movement of the main control valve piston reduces chamber volume in the control valve 22 to pressurize the cylinders 83. However, a small leakage of fluid around the subcontrol valve spool is allowed to the reservoir, so this has to be blocked under pressure failure conditions; Fig. 4 shows the safety valve 81 wherein a piston 99 moves leftwardly due to pressure decrease in a chamber 100 communicating with the accumulator 16, allowing a ball 88, previously held clear of a seat providing communication between an inlet from the valve 53 and the reservoir 12, to block such communication. In Fig. 5 the main control valve 22a is fed directly by a pump 10a allowing fluid return to the reservoir 12a via passages 33a, 36a, 32a, 31a when not actuated. Pedal movement causes gradual closing of the passage 32a to increase pressure to the subcontrol valve 53a (similar to valve 53) up to pump pressure. Upon pump failure, the volume decrease in a chamber 29a of the valve 22a causes pressurization of the wheel cylinders 83a. Here the safety valve 81a is solenoidcontrolled by a switch actuated by a pedal 47a, during extra movement due to such failure, to close communication to the reservoir 12a.

Abstract: 1399950 Colour television ROBERT BOSCH FERNSEHANLAGEN GmbH 7 Nov 1973 [10 Nov 1972] 51639/73 Heading H4F A colour television signal A 0  is comb filtered by delaying it by one line period to provide a signal A 1  and subtracting from the signal A 1  a signal k(2A 1 -A 0 -A 2 ) to provide a chrominance-free signal, where A 2  is the signal A 0  delayed by two line periods and k = ¢ for a signal (PAL) having quarter-line offset and k = “ for a signal (NTSC) having half-line offset. The signal k(2A 1 -A 0 -A 2 ) may be derived from a vertical aperture corrector. The system may be used in a conversion system for converting PAL signals to NTSC signals or vice versa for horizontal aperture correction. A circuit may be provided for comb filtering either PAL or NTSC signals, signal A 1  being applied to a terminal 6 connected to a difference amplifier 5 and a signal ¢ (2A 1 -A 0 -A 2 ) from a vertical aperture corrector being applied to a terminal 1 connected to a switch 2. When receiving an NTSC signal having half-line offset the terminal 1 is connected by switch 2 to contact (a) and hence via voltage divider 3, 4, dividing it by two, to amplifier 5 which thus provides a signal A 1 -“(2A 1 -A 0 -A 2 )=¢A 1 + “A 0  + “A 2 . The chrominance component of this signal is zero as the chrominance components of A 0  and A 2  are of opposite phase to the chrominance component of A 1 . When receiving a PAL signal having quarter-line offset the terminal 1 is connected by switch 2 to contact (b) and hence directly to amplifier 5 which thus provides a signal A 1 -¢(2A 1 -A 0 -A 2 )=¢A 0  + ¢A 2 , the chrominance component of which is zero as the chrominance components of A c  and A 2  have opposite phases.

[Also in Division G2] A method of obtaining isometric drawings of a structure such as a chemical plant comprises building a small scale model of the plant, measuring by means of two telescopes 23, 24 the coordinates on a three dimensional system of each point of interest of the model, storing in a data processor the co-ordinates of each point of interest and additional data concerning the nature of the various components of the structure and data processing the measured co-ordinates and the stored additional data to plot the isometric drawings. The telescopes are displaceable along the axes x, z of the co-ordinate system and the distance of each telescope from the origin of the co-ordinate system is equal to the number of revolutions of its lead screw 9, 10 multiplied by the linear pitch of the lead screw. The telescopes are mounted on vertical slide rails 3, 4 by slides 15, 16, the movements of which along the y axis are controlled by electric motors 27, 28. The rails 3, 4 are mounted on slides 7, 8, the movements of which along the x and z axes are controlled by electric motors 11, 12. Supports 15, 16 enable the telescopes to be tilted at angles of 15, 30 or 45 degrees with the vertical or horizontal so that parts of the model pipework obscured by pipework in the foreground may be viewed. Revolution counters 19-22, for example in the form of rotating perforated discs interposed between photo-cells and light-sources, transmit pulses to a pulse counter according to the number of revolutions of the lead screws. The pulse counter converts the pulse numbers into lengths representing co-ordinate values which are fed to the data processor. The co-ordinate values are fed to the data processor together with additional data such as correcting numbers for those coordinates which have been observed with the telescopes tilted, code numbers indicating a flanged joint, a branch, a valve, &c. and Identification numbers for each individual pipe-line. The data processor computes the total length of pipeline and the lengths of sections between fitting as well as determining the number of fittings and providing a complete parts list. The data are also fed to a drawing machine which plots isometric drawings of the plant as well as sectional drawings in planes parallel to each coordinate plane.
